To all whom 'it 'may concern:

Be it known thatwe, CARL P. BOHLAND and JosnPI-r J. CoNNnLLY, citizensof t-he United States, residing at Superior, in the county of DouglasandState of `\Viscons1n, have invented certain new and usefulImprovements in Molding-Machines, of which the following is aspecification.

Our invention relates to an improvement in molds, and more particularlytothe molds for bins or tanks which are circular in shape and intendedfor storing grain and the like.

The object of the invention is to provide i means whereby the mold canbe raised after the first section of the bin is formed, and the mold,after having been raised the desired distance, is secured or locked uponthe molded article or section, when the mold is again filled with thecement or concrete for building the bin the desired height.

The inventionl consists in certain novel features of construction andcombinations of anV pointed out in the claims.

` In the accompanying drawings Figure 1 is a view in eleva-tion, showingthe concrete structure .and walls of the mold in section; Fig. 2 is avertical'section; and Fig. 3 is a detail view, showing the manner ofconnecting the pipes Which are used as a reinforcement inthe concretestructure.

A, A, represent the uprights and B, B,

.the Walls of the mold which are connected to the uprights A. A baril isrigidly con- `nected to one of the uprights A by means of bolts2'passing through an angle plate 3 connected to Vthe uprights. The otherend of `the bar slides beneath an angle plate 4 and in a recess formedin the annular platform C which extends around the interior of the mold.A tube orrod 5 is received between the walls of the mold B and isembedded in the concrete or cement for form- .ing a reinforcement forthe concrete wall.

The rod or tube extends through an opening formed in the bar 1 upwardlybetween the uprights A. The Urshaped yoke 6 is received around theuprights Aland the ends of the yoke are connected together and held uponthe uprights by plate 7 and nuts 8.

A lever 9 is plvotally connected to one of the uprights A and is alsoconnected to the yoke 6. When the lever 9 is thrown down. wardly againstthe platform 0 the uprights A are drawn together, causing the arts whichwill be hereinafter describedwalls.v vB to be'drawn toward cach other."But when the lever is thrown upwardly practically parallel with theuprights A, the

walls will separate from leach other slightly,

o r sufliciently to allow the mold to be drawn upwardly. 'Pivotallymounted upon the upper surface of the bar 1 are dogs 10, 1-0,

which are adapted to engage the tube 5 forv provided with an annulargroove 14. The

collar is preferably made in two `sections and received between thesections is the hub 15 of a wheel 1G. Upon the hub 15 is an annular rirn17, which is adapted to be received in the groove 14.' A screw-threadedsleeve -18 is received over the tube 5 and is adapted to pass throughthe opening 12 to the beam 11, and the hub 15 of the wheel 16 isscrew-threaded, whereby a screwthreaded engagement'is formed between thesleeve 18 and the wheel 16. Connected to the lower end of the sleeve 18is auide# plate 19 which is provided with forke ends 20, between whichare received the uprights A, 'the plate being held upon the sleeve by athumb-screw 21 which prevents the sleeve from turning. Arms 22 areyformed on the sleeve and pivotally connected to the arms by means oflinks 23 are dogs 25, which dgs are provided with openings throughadapted to engage the rod for locking and retainin the mold in itsraised position. The un er surfacev of the `plate 19 is beveled from thecenter toward the ends, as indicated by the dotted lines 26.

Assuming that the cement or concrete has been poured into the mold andforiued into which the rod 5 extends, and the dogs are the proper shape,and -it is desired .to raise the mold for`bui1ding the wall higher. .Thelever-9 is raised, whereby the walls B are released from the walls ofthe molded article,

Wheel 16 is then turned to the left, which causes the uprights A andWalls B of the mold to move upwardly, sleeve 18 remaining stationary.The Wheel is turned unt-il the walls of the mold have been brought toabout within 6 inches from the top of the molded wall. After thisadjustment has been obtained the lever 9 is thrown down,

constructed with our device, as it can easilyI be adapted to a straightwall, orany other lshaped wail aswell asthe circular wail, and

' raising operation.

"causing the sleeve 18 to be raised causing the walls be brought intoengagement with the walis of the molded article. After this operation ofraising the mold, there will be little oi the sleeve'left for the Thedogs 25 have been supporting the mold during the raising operation, andbefore the screw sleeve is raised upwardly for the next operation, thewheel 16 Will'be continued to move upwardly unt-i1 the plate 19 hasengaged the dogs 10, causing them to firmly grip the tube 5. As the dogs10 continue to move upwardly on the bar 1, the upper end s of the dogswill engage the beveled surfaces of the plate 19, which will cause themto be forced against the pipe or tube 5. After this hasv beenaccomplished, the' wheel 1'6 Will be turned to the right,

dogs 25 released from engagement with the tube. The sleeve will beraised to the de.`

sired height, when the mold can again be raised upon lthe turningr ofthe wheel 3 6 to `the left, after the lever 9 has been raised to itsvertical position. This operation is con# tinued until the wall is madeto the proper height. Of course,

raising or lowering of either the sleeve or Athe mold may be performedat any intermediate point. In Fig. 3 We have disclosed the manner ofconnecting the tubing together. When the top of a tube has been reachedin the molding operation, and it is desired to add another length ofpiping," two short lengths of piping 27 are provided, which larescrew-threaded and connected to which is a coupling 28. .An end of eachof the pipes 27 is adapted to be received Within the tubing 5. After thetwol pipes have heen connected together, they willtake the position asindicatedby the dottedlines, thereby presenting" a, smooth surface forthe dogs 10 and 25 to grip during the operation of raising the mold.

We do not care to limit ourselves to any particular formation of Wa'liwhich may be hence We do n ot care to be iimited 'to the exactconstruction set forth, but Having fully described our invention, whatl. The combination benioved.
